Fishing provides food, income and employment for millions ofpeople. However, fishing has environmental costs that threaten rarespecies, marine ecosystems and the sustainability of theresource.
Based on the research expertise of leading scientists,Commercial Fishing: the Wider Ecological Impacts provides alively, timely and accessible account of fishing activities andtheir impacts on marine habitats, biodiversity and species ofconservation concern. It covers fishing methods that range fromtrawling in the Antarctic to fishing with dynamite in thetropics.
The authors show how habitats such as the muddy sea beds of thedeep sea, kelp forests and coral reefs are affected by fishing andhow birds, mammals, turtles and sea snakes both suffer and benefitfrom fishing activities. They also look to the future, highlightingways to make fishing gear 'environmentally friendly' and askingwhether marine reserves will improve conservation.
